Researchers from the Arizona State University Center for Global Discovery and Conservation Science (GDCS) have developed a new system capable of monitoring carbon emissions from tropical forests with ...

Accurate measurements of surface currents are crucial for coastal monitoring, rip current detection, and predicting the path of pollutants. Several methods exist to measure surface currents, some of ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...

The measurement technique of an aspheric surface is mainly for the surface form and parameters. The surface form is the three-dimensional distribution of the surface in the spatial domain. The ...

Google Earth allows you to measure the distance between two points on the Earth, as well as the circumference of a circular section of the ground — or even the elevation of a mountain. But in order to ...
